To all whom it may amt-em:

Be it known that I, BRUCE FORD, a citizen of the United States, residingat the cityof Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Vented Stop or for-Storage-Battery Jars, of which the fo owing is a specification.

The principal object of the present invention is to rovide acomparatively inexpensive, simp e and efiicient stopper for storagebattery jars which will permit of their ready" filling and also preventsplashing and spraymg.

The invention will be more fully understood from the followingdescription taken in connection with the accompanying drawings in which-4 Figure 1, is a side view of a stopper em-. bodying the inventionshowing the same in application to a battery jar which is illustrated insection. Fig. 2, is a top or plan view of the sto per. Fig. 3, is a viewshowing the parts of t 1e stopper detached and illustrating themrespectively, in said view and in section, and. Fig. 4, is a centralsectional view of the same.

in the drawings 1, is a tubular or cylindrical shell shown as internallythreaded at one end and externally threaded at the other end.

2,, is a hollow conical stopper body shown as externally threaded forengagement with the internal thread at one end of the shell. The body 2,is provided with a milled edge 3, perforated at its apex 4, and at itsbase 5.

In use the external thread of the shell 1, engages a tapped opening 6,in the cover 7, of a jar 8, that contains plates 9.

10, is a sealing compound shown to extend If liquid passed it woulddampen the lower end of the cone. However, bubbles are not there formedand burst in the form of spray because gas such as would produce thisefiect escapes at the openin s 5. Similarl bubbles are not formed at t eopenings 5, or wet inside of the cone in roximity to it trickles down bygravity and runs through the o ening 4:. In this way undesirablespraying rorn the vented stopper is revented. The stopper body may beremove from the casing 1, in order to introduce liquid into the jar 8,through the casing.

Having thus described the invention, what I claim is:

1. A vented stopper corn rising a tubular casing open at eac 1 end andprovided at one of its ends with attaching means, and a detachablestopper body adapted to close the around the base of the casing 1.

should be sprayed or otherwise through the perforation 4, or wet theinside of other end of the casing and consisting of a hollow coneperforated at its apex and having in the wall thereof perforationsarranged near its base, substantially as described.

2. A vented stop er comprising a cylindrical casing througi which liquidmay be introduced and internally threaded at one end, and a stopper bodyexternally threaded for detachable engagement with the other end of thecasing and )rovided with an operating edge and with a hollow coneperforated at its 2. ex and in itscurved wal near its base, sustantially as described.

In testimony whereof I have hereunto signed my name.
